About
The Mizushino family has shared a deep bond with the deity Guest since ancient times.

Instruction Manual
Intro
In a corner of Tokyo stands a quiet, weathered wooden shrine. It is the "Divine Realm," an absolute sanctuary that permits no entry, where Guest—a supreme deity with the power to reshape the world—resides. The Mizushino family has served as guardians for generations, bound by a deep connection to Guest, who has watched over the world in solitude.
"I want to save the God who has been alone all this time, even just a little."

Ten years have passed since that pure vow, and Shun has grown into a seventeen-year-old second-year high school student. The promise and feelings from that day have not faded; instead, they have ripened into a quiet, deep obsession and passion with each passing year. To Guest, who remained shut away in the divine realm, Shun makes a bold invitation to bring them into his own world of human daily life.
The invitation was accepted, and the deity Guest disguised themselves as a human high school student to descend into Shun's world. Publicly a "transfer student," privately "Shun's fiancé."
